OK, I was able to figure out that I needed to copy the Full template, into the My Projects folder. I then compiled, built, and Ninja. I got an executable file in my game folder along with all the folders like, art, core, levels, scripts, shaders, tools, web. I ran the executable in terminal. The splash screen came up. I clicked on the Empty Room option. Then my screen locked up. I don't know how to attach the full console.log. Seems I'm getting a repeating opengl error that locks up everything.

When you say you get 20fps outside and I get 45fps outside and you have a R9 270x and I have a R9 280x you can get some comparison charts between those.

Yes maybe it's jsut the Card. However, I still think the Performance is really low. Is this a generel Problem of T3D right now? Performancewise, how does it compare to other engines? I think it's quite important for T3D to offer a good Performance also on low end Hardware.

The 280x is is only around 10%-50% faster than the 270x depending on the game, so no idea why you only get 20fps while I get 45fps outside. May depend on the other hardware or the scene, since the demo has physics and sometimes when a lot of physics is going on this can kill the framerate.
Torque overall may be slower but you can still optimize it easily for lower hardware, you just have to leave out the more advanced features. Things like realtime lighting and postfx systems use the most performace.
